What will happen to the fat fillers for under eye dark circles is a person looses a lot of weight say 90kg to 60kg , are there silicone based fillers?

In brief:
Fillers more visible

After weight loss the fat fillers might be more visible under the eyes.

At 19, it would be rare to use fat under the eyes. After 30 kg weight loss, there may be many changes in the face benefiting from tightening so that the infraorbital hollows are less troublesome. Silicine injections can harden over time and even extrude making scars years later. Avoid silicone injections especially by the eye.
